Hello! Check the tech-section of this website ( Philco Repair Bench- Philco part values ) and click on bakelite condenser data provided there. You will need the orig part # located on the side of your condenser to match up with the diagrams provided. The diagrams will provide the info you are seeking. Good luck with your Philco restoration!! Icon_biggrin

ckc, part #s 23 &28 are 3903M and 3903P respectively. Each has one .01mfd, 600V cap. 3903M has cap between terminals 4-8 and 3903P has cap between terminals 2-7. Neither cap is grounded, they are by-pass caps. PL
